A developer-friendly epoch and date converter
A Unix timestamp is the number of seconds (or milliseconds) since 1970-01-01 UTC. Turn the values you meet in logs, API responses, and databases into human-readable dates — and back again. Everything runs in your browser.
Values with 13+ digits are detected as milliseconds, avoiding the classic wrong-year mistake.
See one timestamp as UTC, your local time, ISO 8601, and a relative time all together.
Convert timestamps to dates and dates to timestamps, then copy any result in one click.
